Title:
  Please fix CVE-2012-0864 in precise

Status in “eglibc” package in Ubuntu:
  New

Bug description:
  CVE-2012-0864 was addressed in 1396-1 for releases prior to precise,
  but still needs to be addressed in precise.

  From the USN text:

   It was discovered that the GNU C Library vfprintf() implementation
  contained a possible integer overflow in the format string protection
  code offered by FORTIFY_SOURCE. An attacker could use this flaw in
  conjunction with a format string vulnerability to bypass the format
  string protection and possibly execute arbitrary code.

  (debdiff forthcoming)
